HIGH-PRESSURE POWER PRESS.

Application led November 8, 1921.

I accomplish the objects ot theinvention by the devices and ymeansdescribed in the 'following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodinient of the invention is fullyillustrated in the accon'ipanying drawing, forming a part of thisaiiplication, in which:

Fig. I is a detail perspective view of the upper part of a power pressembodying the features oi iny invention, portions of the base and ot thedriving gear being broken away and the screw and stop means being shownin broken sections, certain parts be ing indica ed by dotted lines, thesame being taken angling Afrom the front of the machine.

F II is a rear elevation oi. the upper part of the strrmturi-rJ as seenin Fig. I.

Fig. III is an enlarged detail elevation vien' oi" the reversing screwmeans and the hand actuatedpinion means for controlling the press.

Fig. IV is an enlarged detail horizontalsectional view on line @-4 oi'Figs. I, II and V, showing the worin gear for driving the .nul and thereversible worm for actuating the same in full lines.

Fig. V .is an enlarged detail sectional view on line .Fi-5 of Fig. IV,showing the screw threaded ram, the nut and the worin gear tor drivingthe same with the bearings and supports therefor.

Fig. VI is an enlarged detail sectional viewion line 6--6 of Figs. IIand III.

ln the drawings similar reference characters refer to similar partsthroughout the Vseveral views and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Consideringthe numbered parts of the drawing by their numerals, 1 is thebase, shown tragnientary. 2, 2 are 'the supporting Serial No. 513,813.

columns of the frame carrying the heavy cross trame 3 which is retainedupon the base by the tic bolts l having lock nuts 5 at the top andbottoni. The ram 6 is splined to the cross beam and screw threaded andcarried in the revoluble nut 7. The nut 7 supported in anti-frictionbearings, preferably ot the roller type, within the crossbeam 3 ot theframe.

it. worm gear 8 is keyed to the nut at 9 and is held up by thrust ballbearings 1() on the supporting plate 11. The supporting plate 11 is heldin place by the cap screws 12, see particularly Figs. I and V.

The worm gear 13 on shaft 14 is supported in anti-friction bearings 15in the housing 16 at one side ot the housing 17 for said worin gear, thehousings being provided inrrticularly for the retention of lubricant.

'.lfhe shaft 111 is driven by reverse gear mechanism 18 which is of awell-known marine propeller reverse type, (not necessary here toillustrate as the same can be purchased in the open market) the samebeing controlled by therod'l), which is movable end'wise to accomplishthis result. This rod extends to the automatic control. It linovidedwith a rack 2O and pinion 21 controlled by hand wheel 22 When it isdef-:ired to control the movement of the press by hand.

The rod is controlled automatically from the rock shaft 23, which isprovided with an arm 2e, which is actuated by the conneet- .ing rod 25adjacent stops 26, 27, thereon, such stops comprising locking nutsadjustable on the screw threaded ro 25, thereby permitting very closeadjustment.

An arm 28 with collar 29 surrounding and clamped to the screw threadedram 6 acts upon the said stops for rocking the said rock shaft Adownwardly projecting arm 30 with slot 31 in its ,lower end reciprocatesslide 32 as the means for actuating and controlling the control rod 19to the reverse. gear. The slide 32 is provided wi th oppositely disposedinclined faces 33. 33 'which act upon latches 34, 311 at each side, thelatches being pivoted at 35 on suitable supports 36, 36, through whichthe said rod 19 reciprocates.

The notches 37, 37 of the latches engage collars 38, 38 pinned to thesaid rod 19 by pins 29. Flanges 40 project out from the ranism out ol'gear. rock shaft 42 in bearings 43 is provided said collars to 'engagethe notches37 of the said latches 34. `l-Ieavy compression springs 41,41 are interposed between the slide 32 `and thecollars 38, 38 at eachside thereof.

It will thus be seen that on the up .movement oit the rain 6 the arm 28will be carried up against the stop 27, pulling upwardly on the rockshaft arm 24,1'oclnng the saine and swinging the arm 30 towards theright, as

,seen in Figs. I and III, thereby actuating th'e'fslide 32 andcompressing the spring 41 against the right-hand collar. r1`he rightihand inclined `tace 33 also slides under the inclined end of the latch34 and eventually lifts the Isame out of engagement with the4 collarbyliftingv the notch 37 away from the flange 40. 'Ihespring 41Uthen shootslthe Y rod"19 to the right and throws the reversible gear 18 1intoaction, driving the worm and carrying theram downwardly until the arin28'c`ontacts with the stop 26 and toi-ces the parts Ve'nu'n'i.erated inthe contrary direction until the' leiith'and latch is released and thecont-rol rodshot in that direction reversing `the reverse gear andcausing the ram to rice. The speed is preferably higher on the reverseor up direction and is gaged so that an operator hastime to place workunder themram and hold in place for the action of `the ram and to removethe same when the 'rain rises and place a succeeding article 1n with `anactuating handle 44 and with an arm 45 to which is pivotally connectedrat 46 a pair of links, 47, 47. These extenddowir wardly at each side of'the rock shaft 23 and engage pins 48,48 on the ends of the latches 34.Slots 47 are in the ends of the links 47 to permit the latches toplayfreely up and down therein and at the same tiinefenable the latchesto be elevated by the depression of the handle 44, (see Fig.- III).k Thehandle 44, `when depressed, snaps under a catch 44 (see Fig. II) tothrow the automatic reverse permanently out of gear. A handlever 23T`provided for the rock shaft 23 to start the machine and put theautomatic mechanism into operation. It is clear that when the machine isyat neutral, as seen in Fig. III, it will remain so untillsomething/sets, it inmotion, which is done by depressing the, lever 23.gear sucha manipulation will not be necessary. It is possible `to stopand start by the manipulation `ot this lever 23 as well las by themanipulation of the hand wheel 22.

The pinion 21 is preferably nf'ithdrawn from engagement whentheautomatic device is ing used.

I have shown the double control 'lor the shiftconnection to the reversegear, but it is clear that this couldl be adapted :for use as.

a single control for the downstroke where accuracy is required and thehand ot the operator ,or other stop means Amight be pi'ovided forwtheend of ythe upstroke.

I have described my `improved power press` in the form in which Iprefer, but clearly the parti can be greatly modified and manyeaturesvaried without departing from my invention. I desire to claim theinvention in the speciiic vform illustrated-and also broadly as pointedout in the appended claim,

Having thusdeseribed my inventiomwhat .I claim as new and desire tosecure by Let- J AMES G. COLLINS.
